Example of zero sequence CT scaling

Zero sequence CT scaling (ZCT scaling) is done when a zero sequence CT instead of a ring core CT is

part of the measurement connection. In such a case the zero sequence CT should be connected to the

I02 channel which has lower CT scaling ranges (see the image below).

Figure. 5.2.1 - 63. Connections of ZCT scaling.

Troubleshooting

When the measured current values differ from the expected current values, the following table offers

possible solutions for the problems.

NOTE!

TE!

If you work with energized CTs, extreme caution needs to be taken when checking the

connections! An opened CT secondary circuit may generate dangerously high voltages. A

"buzzing" sound from the connector can indicate an open circuit.

Problem

Solution

The measured current

amplitude in all phases

does not match the

injected current.

The scaling settings may be wrong, check that the settings match with the connected current

transformer (

Measurement

→

Transformers

→

Phase CT scaling). Also check that the "Scale meas.

to In" is set accordingly. If possible, check the actual CTs and their ratings as there may have been a

need to change the original plan.

The measured current

amplitude does not

match one of the

measured phases./

The calculated I0 is

measured even though

it should not.

Check the wiring connections between the injection device or the CTs and the relay.
